[gtkmm] treeview get_selected_rows crash

[Tim Flechtner <timf trdlnk com>]

using gtkmm-2.2.5,  i have a segment of code, intended to scroll a 
treeview to a selected row:

TreeModel::Children rows = m_windows_store->children();
for(TreeModel::iterator i = rows.begin();
    rows.end() != i;
    ++i) {
  if((*i)[m_windows_record.m_record_column] == window_record) {
    Glib::RefPtr<TreeSelection> selection = m_tree_view->get_selection();
    selection->select(i);
    list<TreeModel::Path> paths = selection->get_selected_rows();
    list<TreeModel::Path>::iterator path = paths.begin();
    m_tree_view->scroll_to_row(*path);
    return;
  }
}

which is in a function which is connected to a signal emitted when a 
window receives focus in.  on solaris x86, this seems to function 
correctly, but on linux x86, it crashed with the stack dump below.  i 
suspect i'm using an invalid smartpointer or iterator, but i can't find 
my glitch.  can anyone see what i'm doing wrong?

thaks!
